Read a recap of the fourth Republican presidential debate, as live-blogged by MarketWatch’s Rob Schroeder. It was held in Milwaukee, Wis., and featured eight candidates. Fox Business Network and The Wall Street Journal were the hosts.

Not on the main stage tonight: Chris Christie, Bobby Jindal, Mike Huckabee and Rick Santorum. Those four met earlier tonight in an undercard debate – with Christie and Huckabee on that stage after failing to make the main-stage cut in polling.

Heading into tonight’s debate, Trump and Carson are basically neck and neck in national polls, with Marco Rubio in third. Jeb Bush, once the frontrunner of this GOP pack, is back in fifth in the RealClearPolitics average. He needed a good performance in the last debate, and observers said he didn’t have one. Let’s see how he does tonight.

There’s going to be lots of scrutiny on Ben Carson tonight. The normally mild-mannered ex-surgeon slammed reporters last week after a Politico story questioned his statements that he was offered a position at West Point. He’s making hay out of that and other stories tonight, mocking the media in a series of tweets.

Meanwhile, reporter Jeff Bartash wrote this piece today, saying there’s little evidence that financial probity, or a lack of it, has anything to do with how presidents govern or how the public sees them.

The GOP candidates might have a hard time coming up with statements bashing the economy — at least as shown in last week’s jobs report. The labor market heated back up in October, with the U.S. adding a stronger-than-expected 271,000 jobs.

Now a CEO-pay question for Rand Paul, who says it “absolutely” matters that income inequality is rising — especially in cities, states and countries run by Democrats. Plus, he bashes the Fed — a favorite Paul target.

Here we go: media question for Carson. Are you worried your campaign is now being hurt? A little humor from Carson: Thanks for not asking me what I said in the 10th grade. But I do have a problem with being lied about. And he’s ripping Hillary Clinton over the Benghazi attack.

Rubio takes a swipe at the U.S. corporate tax rate, saying it’s the highest in the industrialized world. But he’s not mentioning the effective rate corporations pay, given deductions and credits. Check this out for more.

Paul repeats his line he wants a government so small “you can barely see it” — and says his tax plan is the only one that balances the budget. And it gets rid of the payroll tax. If we get rid of the payroll tax, everybody’s going to get a tax cut, Paul says. He says the business tax (payroll, presumably) pays for Social Security.

Trump is ripping currency manipulation and the Trans-Pacific Partnership for not including steps against it. The Treasury Department says a side agreement includes strong steps for addressing it, however. Read arguments over currency here.
